SPECIFICATION forming part of Letters Patent No. 403,114, dated May 14,1889.

Application filed September 18, 1888. Serial No. 285,723. (No model.)

To aZZ whom z'/ may concern:

Be it known that I, HENRY MAETAIN KINGS- BURY, a citizen of the United States, residing at Middletown, in the county of Lake and State of California, have invented a new and useful Improvement in a Combined Plow, Cultivator, and Seeder, of which the following is a specification.

My invention relates to an improvement in a combined plow, cultivator, and seeder; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is a top plan view of a combined plow, seeder, and culti- Fig. 2 is a side elevation of the same. Fig. 3 is a vertical longitudinal sectional view taken on the line .fr of Fig. l. Fig. 4 is a vertical transverse sectional View taken on the line 'y 'y of Fig. l. Figs. 5 and 6 are detail views.

A represents a rectangular frame, which comprises a pair of beams, B, a cross-beam, C, connecting the same near their front ends, and a cross-beam, D, connecting the beams B near their rear ends. Arranged obliquely under the frame at a suitable distance from one of the front corners thereof is a plow-beam, E, the ends of which are bolted to the under side of one of the beams B and to the under side of the beam C. Secured to the beam E, and arranged at suitable distances apart, is a series of turning-plows, F, the mold-boards of which incline in the same direction, and thereby the said plows are adapted to throw their furrows all in the same direction. To the inner sides of the beams B, near the rear ends thereof, is pivoted'a pair of arms, G, by means of bolts H.

I represents a pair of clamping-plates,\vhich bear against the inner sides of the arms Gr, and are secured to the inner sides of the beams B by means of the pivotal bolts H and bolts K, which pass through openings in the ends of said plates.

L represents a cylindrical roller, which has trunnions or spindles M projecting from its ends at its center and journaled in openings in the lower ends of the arms G.

N represents a pair of brace-levers, which have their lower ends j ournaled on the projecting ends of the roller-spindles, and are provided at their upper ends on the lower the brace-levers N pass between the said plates and the outer sides of the beams B, and the teeth or recessesof the said levers are adapted to engage the bolts R, which secure the lower ends of the plates P, and thereby secure the arms G at any desired adj ustment, either in a vertical or in an inclined position, and thereby enable the rear end of the frame to be raised or lowered.

S represents a bolster, which is arranged transversely between the beams B on the front side'of the beam C, and has a plate, T, secured to its under side. The said plate is longer than the said bolster, and the ends thereof are bent upward at right angles to form vertical arms U, which bear against the outer sides of the beams B, and thereby arrange the ends of the beams B between the ends of the bolster and the arms U. The latter are provided each with a vertical series of openings, V, and a pair of bolts, NV, pass through one of the said openings in each arm and enter the beams B, and thereby secure the bolster to the beams and adapt the bolster to be raised or lowered at the front end of the frame.

X represents a truck, which comprises an axle, Y, a pair of supporting wheels or rollers, Z, journaled on the spindles of the axle, v

the block A secured on the axle, and a circular plate or ring, B', secured on the said block. The rear end of a tongue, C', is secured to the center of the block and axle and to the ring or plate.

D represents a king-bolt, which extends through the centers of the axle and block, and has its upper end extending for a considerable distance above Ithe block. The lower end of the king-bolt is connected to the under side of the tongue by means of a hammer-strap, E. The said kingbolt passes through a vertical opening which is made in the bolster S near one end thereof, and serves to pivot the truck to one of t-he front'corners IOO of the frame A. bolt extends normally above the bolster, and is engaged by a plate or arm, F', which is bolted on the beam C and projects forward therefrom.

l' represents a sleeve or knuckle, which is Swiveled on the upper end of the king-bolt. To the upper end of said sleeve or knuckle is fulcrumed a lever, ll', the inner end of which is connected to the center of the bolster S by means of a chain or link, l'.

From the foregoing description it follows that the front end of the frame may be raised or lowered on the projecting upper portion of the king-bolt by means of the lever ll. A hook or detent, K', projects from the front end of one of the beams B, and is adapted to engage the said lever when the front end of the frame is elevated, so as to raise the plow from the ground, and thereby maintain the frame in this position. By adjustingl the front end of the frame vertically on the bol ster, and by adjusting the rear end of the same, by means of the swinging arms G and the rack-levers N, the height of the frame may be regulated so as to c ause the plows to operate in the ground at any desired depth.

L' represents a rock-shaft, which is arranged transversely un der the frame at a suitf able distance in advance of the roller, and is journaled in a pair of hangers, M', that depend from the beams B. A series of cultivating or stirring plows, il, are secured to the said rock-shaft, and to one end of the rockshaft is secured a lever, O'.

P' represents a spring-arm that is secured to the inner sides of one of the beams B, and is provided at its free end with a series of notches, which are adapted to engage the lever O', and thereby secure the same in any desired position, and consequently enable the cultivating or stirring plows to be retained at any desired adjustment.

R' represents a trough or hopper, which is arranged. diagonally on the frame, and has its rear end secured to the beam D and its front end secured on ablock, S', thatis bolted on one of the front corners of the frame. The said trough or hopper is parallel with the plowbeam E and may be arranged at a slight inclination. In the bottom of the hopper, at suitable regular distances apart, are openings T.

U' represents a plate, which is arranged under the bottom of the hopper, and has its side edges guided in grooves on the inner sides of a pair of bars, V, which are secured to the lower side of the hopper. The said plate U' has a series of openings, XV', which are adapted to register with the openings T'.

Freni one end of the plate U' projects a screw-arm, X', which passes through a central opening in a yoke, Y', that is secured to one end of the hopper. Adjusting-nuts Z are screwed onto the screwarm and bear against the front and rear sides of the yoke. By turning the said nuts the plate U maybe The upper end of the kingmoved longitudinally under the bottomof the hopper, so as to cause its openings to register with those of the hopper or to move partially past the same, so as to regulate the size of said openings, and consequently regulate the quantity of seeds that are dropped from the hopper. A cutso'if plate, A2, is supported under the plate U' and provided with openings B2, which are adapted to register with the openings of said plate U' or to move past the same. A lever, C2, is connected to the cut-oft plate and adapted to operate the same and cause the latter to open or close the openings of plate U'. v

D2 represents a roekshaft, which is arranged longitudinally in the hopper over the center of the same, and has its bearings in the ends of the hopper. Stirring-arms E2 project from one side of said rock-shaft and are arranged over the openingsin the bottom of the hopper, and from the opposite side of the rockshaft projects an arm, F2.

G2 represents an arm that has its front end pivoted to a saddle or clip, H2, thatis pivoted on the beam D at a suitable distance from one end thereof. The rear end of the said arm is forked, andin the said forked end of the arm is journaled a :friction-wheel, l2, the shaft of which has a crank, K2. A pitman, L2, connects the said crank to the arm of rock-shaft F2, and the friction-wheel l2 bears normally on the roller, so that rotary motion of thelatter is communicated to the said friction-wheel, and the crank thereof an d pitman impart rocking movement to the rock-shaft D2, and hence cause the stirring-arms of said rock-shaft to feed seeds from the hopper through the openings in the lower side thereof.

L2 represents a scatter box or trough,which is arranged directly under the hopper and is supported by a pair of hangers, M2, which depend from the block S' and from the beam D. The said scatter-box is V-shaped in cross-section, and an openingis left between the lower edges of its sides, which extends its entire length. The seeds which drop from the hopper R when the machine is in operation strike the sides of the scatter-box and pass through the opening' in the lower sides thereof before reaching the ground, and are hence distributed evenly over the ground and are prevented from falling in bunches.

A chain, N2, connects the lower end of the king-bolt to the plow-beam E at a point in line with the. center of frame A, and thereby causes the draft to be applied directly to the plow-beam, and hence to a very great degree relieves the king-bolt of strain.

A combined plow, cultivator, and seeder thus constructed is adapted to prepare the soil and plant the seeds at a single operation. rlhe plows F serve to plow the ground, the seeds are dropped by the distributing mechanism onto the freshly-plowed ground as soon as the furrows are turned, the stirring or cultivating teeth or plows serve to cover the seeds, and the roller pulverizes the clods IOO IIO

said arms, the brace-arms N, pivoted to armsv G, and having the adj listing-notches O engaging studs R projecting from the frame, the diagonally-arranged hopper supported on the frame, the rook-shaft thereon having the stirring-arms and the arm F2, the arms G2, pivoted on the frame, the roller I2, journaled in said arms bearing on the roller L and having the crank, and the pitman connecting the crank to the arm F2, substantially as described.

2. The frame having the supporting-truck at the front end, the roller L at its rear end, and the diagonally-arran ged beam with ploWs, the hopper diagonally on the frame and having the rock-shaft with stirring-arms and arm F2, the pivoted arms G2, With roller I2, journaled therein, bearing on the' roller L and having the crank, the pitman connecting the latter to the arm F2, the scatter-box arranged under the hopper, and the shaft L', arranged transversely in the frame in rear of the hopper, and having the stirring-plows N and the lever O secured to the said shaft to adjust the stirring-plows, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aiiXed my signature in presence of two Witnesses.

HENRY MARTAIN KINGSBURY.
